Hakuoro

Hakuoro wears an irremovable mask over the top part of his head extended down to just under the eyes. He is found badly injured by Eruruu, Aruruu, and their grandmother Tuskur in a nearby forest and they nurse him back to health. It is soon apparent that he has lost all of his memories, and he additionally finds that the state of the world varies significantly from his expectations. In place of his forgotten name, he is given the name Hakuoro.

Spoiler

(白皇, meaning "White Emperor" in Ainu; this was also the name of Eruruu and Aruruu's father.)

His main weapon of choice is a large metal fan given to him by Tuskur. He quickly captivates and gains the trust of those around him, and soon finds himself in a growing position of leadership.
